(\partial)/(\partial y)(cos(2y))

\frac{\partial}{\partial y} (cos (2 y))

- sin (2 y) \cdot 2

Solution steps

\frac{\partial}{\partial y} (cos (2 y))

Apply the chain rule:

- sin (2 y) \frac{\partial}{\partial y} (2 y)

= - sin (2 y) \frac{\partial}{\partial y} (2 y)

\frac{\partial}{\partial y} (2 y) = 2

= - sin (2 y) \cdot 2

\int_{1}^{e} x^{3} \cdot ln (x) d x

(1 - x^{2}) \frac{d y}{d x} = 2 y

y e^{- x} \frac{d y}{d x} = x

\frac{\partial}{\partial z} (x y + z^{3} x - 2 yz)

\int 18 cos^{2} (89 x) d x
